You love the ocean. We love the ocean. Let’s work together to protect it. (PC GGraphics)

Valentine’s Day is all about making sure we don’t take the people we love for granted. Sometimes it feels as though we’re taking the ocean for granted, even though it’s the 71% of the planet that gives us the air we breathe, much of the food we eat, the way we transport goods around the globe, and supports the miraculous wildlife that sparks so much joy. How can we show our love for the ocean?

Right now, people are pulling together to show their love for our endangered orcas any way they can. We use science to find solutions that help us protect endangered species while supporting the people who earn a living from the sea. We are working to reduce bycatch of dolphins, whales, and other ocean creatures by making fisheries more sustainable. Our ongoing efforts to measure and reduce ocean noise can make it easier for whales and dolphins to find food, mates, and navigate an increasingly noisy ocean. Our work on dolphin health provides a glimpse into which pathogens may affect whales, dolphins, and other marine mammals in the Pacific Northwest, and aims to draw a direct link between what we dump into the sea and how the ocean ecosystem is affected.

You don’t have to be a marine biologist to have a positive impact on ocean conservation. The choices we make as consumers can have a ripple effect that encourages industry and policy-makers to embrace ocean-friendlier practices.

Here are five ways to show your love for the ocean. What did we miss? Please share your ideas in the comments!

Reduce your plastic use. Pass on the plastic straw and use re-usable cups. Some of our favorite go-to thank-you gifts are these custom Oceans Initiative pint cups and coffee mugs from our friends at MiiR.

Buy locally and support local artists: 90% of everything comes to us from ships, which are important sources of carbon emissions and underwater noise. Buying locally reduces our shipping footprint. This year, a lot of our gifts include sweets from Seattle-based Joe Chocolates and custom orca stickers from the talented artist, Sophia Trinh. Sophia even offers painting classes, so you can give the gift of experiences, not things.

Choose and support sustainable seafood: Ask your local grocer, farmer’s market, and restaurant about the source of their seafood. It makes a difference. Aim for wild, locally caught seafood that has MSC certification. If you already do this, you can go further to help southern resident killer whales. In the wake of the tragic story of Talequah and the ongoing struggle of the orcas, Chef Renee Erickson made a bold decision last summer to pause serving Chinook salmon in her restaurants. We love giving Renee’s excellent cookbook to our friends and family. Feeling bold? Eat invasive species!Totally guilt-free eating. You’re doing the ocean a favor.

Get out and enjoy the ocean! Go for a walk on the beach, organize a local beach clean-up, surf, paddle, sail, learn about a new whale, fish, or other sea creature, paint or create your favorite ocean art. Have a nap on the beach.

Find a marine conservation nonprofit whose work you like, and support it. Spread the word about their work. Convince a friend to support it. Make a charitable donation in the name of someone you love. It doesn’t have to be us (but we’d be thrilled if you did support our work, of course). Honest. Find the group whose mission sings to you, and get involved.

Pacific Northwest classic gifts (clockwise from top left): Chef Renee Erickson’s cookbook is a love song to the Pacific Northwest; Sophie Trinh’s whale stickers and paintings are magical (& she even offers painting lessons); Joe Chocolate is a sweet, local company; and MiiR’s reusable cups and mugs are lovely and handy in a town that runs on coffee. What are your go-to gifts?

We tend to think of the air-water interface as a barrier to noise. Planes fly over the ocean all the time, but conventional wisdom tells us that most of the sound bounces off the surface of the ocean, and has little impact on the whales and dolphins that swim beneath the surface. A classic paper from 1972 tells us we only need to worry about airplane noise in a narrow cone under the flight path.

Planes fly pretty quickly of course, so any noise exposure is fleeting. But during the busiest periods, we recorded planes taking off every 3 minutes! Below is a map of runways, with coastal runways (<10 m above sea level) in red.

We conducted this study during Nyepi, the Balinese Day of Silence. We did not expect to be able to hear airplane noise over background conditions, but we got lucky. Did you know that fish have a chorus of song, just like the dawn chorus of songbirds? Check out the sounds of fish singing below:

And this is the sound of a small boat passing by our hydrophone. In the last few seconds, you can hear the roar of a jet aircraft taking off from the nearby runway of Denpasar airport, Bali, Indonesia.

In August, part of our team traveled to the Broughton Archipelago off the coast of northern Vancouver Island to continue our long-term study on Pacific white-sided dolphins. This study is multi-faceted. We are studying the health of the population by taking dorsal fin photos for statistical analysis, but we are also studying the health of individuals by looking for pathogens in exhaled breath. We’ve just celebrated the 10th anniversary of this study, but we made a few changes along the way. This year, with the help of Alimosphere, we were able to look at dolphin pods we encountered from a new perspective through the use of Unmanned Aerial Systems (UAS), also known as drones.

This year, we are sponsoring our research associate, Natalie Mastick, to start an exciting PhD project in marine parasite ecology. As she explains in a recent blog post, taking photos of dorsal fins is a non-invasive way to study the population that allows us to identify individuals that we can use as statistical samples in models to estimate survival rates, and population size and trends. High-resolution dorsal fin photographs show us distinguishable details such as nicks, scars, and markings that help us to recognize individuals from year to year. The Pacific white-sided dolphin study launched by our co-founder, Dr Erin Ashe, has involved taking, processing and matching dorsal fin photos to previous catalogues since 2007. Some individuals have been seen in the study area since the 1990s, and we have seen one pair of dolphins together on two occasions 17 years apart.

As a continuation of a study started by Erin in 2015, we also spent much of our time collecting exhaled breath samples from these dolphins. We collect breath samples by positioning a long pole with a petri dish attached to one end over a dolphin as it surfaces and exhales. This is a tricky activity that involves a knowledge of dolphin surfacing patterns, careful boat handling, precise timing, and skillful maneuvering on the bow of the boat. Despite the difficulty, our team was able to collect many breath samples that we will use to assess the pathogens (e.g., viruses, bacteria and fungi) this population has been exposed to. Ultimately, we aim to let the health of the dolphins tell us something about the health of their environment. Understanding how pollutants impact marine mammals and their habitat is essential to informing recovery efforts and monitoring ecosystem health.

Next year, we are hoping to invite Alicia Amerson from Alimosphere to the Pacific Northwest to join us in the field again for a workshop on using UAS for noninvasive marine mammal research. We aim to offer this opportunity to other women in marine mammal science, and to our entire staff. We hope this will provide us with a new tool for collecting breath samples in the future, in a continuation of our efforts to use minimally invasive field research techniques. As we close out our field season, we are so thankful for the support we have received to do this important work.

This summer, from mid-July to the end of September, we studied southern resident killer whale behavior under varying levels of boat and ship traffic. (This is an extension of our 2017 field season with OrcaSound). The Port of Vancouver has asked ships to slow down to less than 11 knots as they transit Haro Strait. Reducing ship speed can reduce shipping noise underwater, but slower speeds mean those ships take longer to transit the area. Working with Port of Vancouver and SMRU Consulting, we are exploring how whales navigate that trade-off between noise level and duration of exposure.

Do the whales find more salmon if they are exposed to a little bit of noise for long periods of time? Or is it better to get the noise over with quickly?

Reducing noise is especially important because endangered southern resident killer whales (SRKW) feed in Haro Strait in the summer, and our work has shown that vessel noise disrupts killer whale foraging. While missing one meal might not seem like it would have long-lasting or population-level effects, Haro Strait is a noisy place, which may result cumulatively in many lost meals for the killer whales. We had our team on the western hillsides of San Juan Island all summer to track killer whales in an effort to find out if and how their behavior changes with the slower, quieter ships.

To track these whales, we used an instrument called a theodolite. You may have seen them on construction sites or traffic surveys. A theodolite has a telescopic lens that we use to track killer whale movement. After setting a constant reference point, the theodolite can determine the angle between the reference point and the whale we’re looking at. It gets the vertical angle from a gravity-referenced level vector. A computer connected to the theodolite can use those two angles (along with the precise location and elevation of the theodolite) to estimate distances and fixed positions of objects on the ocean’s surface (whales, ships, etc). Your geometry teacher was right—this math does have real-world applications. And we can get all of this fine-scale information noninvasively, without another research boat confounding the effect we are trying to measure. This year, the developer of Pythagoras software generously shared code to let us integrate extremely high-resolution AIS data on the movement of ships, so we could automagically collect precise and accurate data on the ships, while having our expert observers concentrate on measuring the whales’ behavior.

In 2017, the killer whales were worryingly absent from the islands much of the summer, which left us with a small sample size. In fact, for the month of August 2017, the SRKWs were nowhere to be found. This year’s longer field season produced much more data. There were 29 days with whales present around San Juan Island. We had tracking stations set up in three locations along the west side of San Juan Island: County Park, Hannah Heights, and Cattle Point, which allowed us to get close to continuous tracks along Haro Strait. We are excited to analyze the data, which should allow us to determine more about killer whale behavior in the presence of these slower ships.

This work felt profoundly important this year, in a season riddled with heartbreaking news about the endangered southern residents. J35’s calf died shortly after being born, and the mother mourned the loss of her offspring by pushing around the carcass for 17 days. J50, the youngest individual in the southern resident population, was found to be critically malnourished. NOAA launched the first attempt to supplement a southern resident killer whale’s diet with additional fish. Unfortunately she has not been seen since September 7 and is presumed dead. It is abundantly clear than additional conservation effort is needed, and our team worked hard to make this field season count, both in the field and on the Southern Resident Killer Whale Task Force.

This work wouldn’t have been possible without a super pod of a team. The Oceans Initiative team was led by Erin and Rob, and consisted of our employees Laurel Yruretagoyena, Natalie Mastick, and Laura Bogaard, as well as Toby Hall, Sarah Colosimo, Jess and Chris Newley, and Elizabeth Robinson, who provided additional field support.

Thank you, as always, for supporting our efforts to keep orca habitat clean, quiet, and full of salmon.

We need to recover Chinook salmon stocks throughout the whales’ range.

We support all efforts to do so. We support dam removal, where this will get more salmon into the environment. We applaud the recent announcement to reduce salmon fishing quotas until the whales recovery, which will reduce our competition with the whales. While we wait for those measures to take effect, we need your help to give the whales a fighting chance to find as many of those salmon as possible in a noisy ocean.

We have found that killer whales are more vulnerable to disturbance when they are feeding than when they are travelling from A to B. They also need more salmon. We have identified areas that whales use preferentially for feeding. (One is called Salmon Bank. We have a feeling the whales knew this before people did.) We need to bring together all dedicated datasets we can use to identify areas where the whales are finding salmon, so we can prioritize those for protection. Protecting key feeding areas is essential to protecting the whales.

Please support our efforts to keep orca habitat clean, quiet, and full of fat, wild salmon.

PS Thanks to our team, especially Toby Hall, for the great footage, and to our friends at SeaLegacy for help editing this video.

Southern resident killer whales are in decline. Our recent population viability analysis on southern resident killer whales predicted that, if threats remained constant, it should take several decades for the population to decline from 80 to 75 whales. In fact, that decline took only three years. We fear that the decline is accelerating, and we may be reaching a tipping point.

By studying killer whales from land, we can measure their responses to noise without adding the noise of a research boat to the equation. We use noninvasive techniques to measure swimming speeds, breathing rates, and other behavior. Our work on both northern and southern resident orca has shown us that the whales spend 18-25% less time feeding in the presence of boats than in their absence.

We recently joined an international, interdisciplinary study to understand the relative importance of the three main threats to recovery in the endangered killer whale population. The whales are facing a perfect storm of threats–not enough salmon, too much noise, and too many toxic chemicals in their bodies–but lack of prey is at the eye of the storm. This research shows it will take 30% more big, fatty, Chinook salmon than we’ve seen on average over the last 40 years for the population to reach our recovery goals. That will take time, but we have to start now. Meanwhile, reducing noise and disturbance can help make it a little bit easier for whales to find the salmon we have now. In the coming months, we will be revisiting our study on identifying critical foraging areas in the Salish Sea and strengthening their protection.

Knowing how many animals are in a population is at the cornerstone of many conservation and management decisions. For whales, dolphins & porpoises, ship time to estimate abundance can be prohibitively expensive — often running into the tens of thousands of dollars each day.

We published an open access paper introducing our Animal Counting Toolkit approach. Wherever possible, the approach prioritizes free software and tools. Our audience is the community of marine naturalists and scientists who may need a bit of guidance to ensure that their observations could be turned into a useful biodiversity monitoring program. We hope the Toolkit finds an audience among NGOs, grad students, coastal communities, and researchers working in countries where funding is severely limited. The US just passed a rule requiring countries to demonstrate that their fisheries are sustainable in terms of marine mammal bycatch. This rule affects $20 billion/year in seafood trade. It is driven in part by a need to level the playing field for US fisheries that have to comply with the Marine Mammal Protection Act and are competing with fisheries that are not MMPA-compliant. Used wisely, the new trade rule will use the purchasing power of the US market to create incentives to improve fisheries sustainability and transparency. But if it is imposed too harshly, and without funding for low-income countries to comply, the US risks penalizing countries that can least afford to take an economic hit. Our Animal Counting Toolkit was motivated in part by this new rule. We want to fill in important data gaps around the world, but we also see value in using this toolkit to help build local and regional capacity for countries to begin to do the kind of surveys that will be needed to demonstrate compliance with this new seafood trade rule. Our hope is to see countries actually improve sustainability of their fisheries, so that we reduce the number of marine mammals killed in fisheries while improving economic opportunities for people who earn their living from the sea.

“I look at pictures of dolphins all day,” is my most common answer when asked what I do for work.

This dolphin has a well-marked dorsal fin, which we will match against thousands of photographs in our database. This photo was taken under research permit with a telephoto lens and cropped.

It’s an over-simplified statement, albeit accurate, and it usually leads to many follow-up questions. The most frequent being “Why?” That’s a fair question. I then proceed to explain how by looking at photos of the dorsal fins of dolphins, I can identify individuals, which can be used in calculating population estimates and survival rates. I am usually surprised by the awe that this explanation inspires, as I am somewhat numb to the task after several months of photo analysis. “You can really tell dolphins apart like that?” They have a point; photo-identification is quite remarkable when you think about it.

Photo-identification (photo-ID for short) is a non-invasive way to study marine mammal populations. It’s been used for both cetaceans (dolphins and whales) and pinnipeds (seals and sea lions), and requires a high-resolution photo of each individual. Photo-ID is an effective way to determine individuals based on coloration, markings, scars, fin shape, nicks and notches. For humpback whales, the underside of the fluke is the most recognizable feature, which is can be photographed as the whale dives. For dolphins, one of the most recognizable features is an individual’s dorsal fin, visible as the dolphin breathes at the surface.

Oceans Initiative has been taking photos of these dolphins since 2007, which is not an easy feat. Pacific white-sided dolphin are fast and can often travel in large pods of hundreds of animals. Erin, Rob, and their dedicated field team have a ton of experience taking photos of these animals, which provided me with a hearty collection of over 10,000 photos to process. One by one, I went through and determined the quality of each photo. Obviously when photographing hundreds of dolphins quickly surfacing and diving, not every photo will be useable for a photo-ID catalog. I found the photos in which fins were in focus, parallel with the camera, and mostly visible (not partly submerged or covered by water or other dolphins) and then looked carefully at each fin to determine its distinctiveness.

It never ceases to amaze me how different dolphin fins can look. A dolphin can have a single little notch at the base of its fin that makes it completely distinct from the rest of the dolphins seen that day. The combination of scarring, nicks from other dolphins, entanglements, killer whales, and normal wear and tear provide an endless permutation of unique fins. I visually assessed each high-quality photo and determined if the fin was not distinctive, somewhat distinctive by temporary marking or discoloration, moderately distinctive, or highly distinctive. Moderately and highly distinctive fins can be used to identify an individual over longer temporal scales.

Once the fins were scored for distinctiveness, it was then my job to match them to other fins within that encounter, and lastly between encounters from that season. When matching between a single encounter, it’s a lot like a game of memory. You know you’ve seen that fin before, you just need to remember where in order to match them. Once the fins are matched within an encounter, I compile a “best of” folder with all of the identifiable individuals observed in that area to match to the other encounters.

When you include the variable of time, then it becomes more like a game of 6 differences, in which you need to spot what’s changed in a fin over time. Except instead of having two fins that you know are just slightly different versions of the same fin that you’re comparing side-by-side, you need to look through the entire catalog to determine if a fin has actually changed since last identified or if it’s a new individual. Though that’s a fun challenge, it is unlikely that a fin changes much over the course of a few weeks, which means matching fins across encounters is a little easier than across years.

To match fins across encounters, I compile all of the moderately and highly distinctive fins from each encounter and look for individuals seen more than once. The 2016 field season provided over 1000 identifiable photos, which were then compared to each other to determine if there were matches. This is where your imagination comes into play. Looking at these fins enough, you start to see shapes in the nicks and notches and fin shape. There was a fin with a distinctive nick towards the top that looked like the profile of a person yelling. There was another that looked remarkably like a bicep. There was one photo in which a fin caught the light just right and looked like it was reflecting back the shape of a storm trooper.

Reading that back sounds like I’ve kind of lost it. Looking at fins enough might do that to you! But overall, being able to put a minimum number to the dolphins seen last season (think about all the dolphins we couldn’t photograph and the fins that weren’t distinctive enough to match!) is incredibly rewarding, and completing each step of the processing myself was oddly satisfying. I’m hoping we can get a comparable number of photos in 2017, and look forward to seeing some familiar fins in the field.

A family of orca (killer whales) works together to find food off northern Vancouver Island. (Photo taken under research permit, zoomed and cropped.)

One of the things we admire most about orca or killer whale cultures is their commitment to teamwork. They work together to find food, coordinate travel, and thrive in a cold, dark environment where prey are easier to find using sound than light. These whales serve as a great template for people working together to tackle some of the world’s most pressing environmental problems, including unsustainable fishing, climate change, and ocean noise. These are challenging times.

As we enter World Oceans Week, we are inspired by the team at Sea Legacy, including the amazing conservation photographers, Cristina Mittermeier and Paul Nicklen. In words and in deed, they show that we can accomplish more #together than we can as separate voices. Taking a cue from Paul and Cristina, we’d like to offer the Oceans Initiative team three ways to help during Oceans Week.

Spread the word. We do “use-inspired science” to guide effective conservation of marine wildlife. By definition, you are a key part of the research questions we ask, and what we do with the information we produce. We can’t do this without you. We’d love to hear from you. Please comment on this blog, or share it with your friends. Sign up for our newsletter. We never share lists, and we won’t fill up your inbox. Encourage your friends to like us on Facebook, and actually click the “follow” button to see what we post. We’d love to hear from you on Facebook, because the platform lends itself to back and forth conversations. Our Twitter feed is interactive, and light, but focuses on emerging science on marine conservation and solutions. We have a large and growing audience on Instagram, and we’d love to see you there. These sound like trivial things, but they matter. Many funders use social media metrics as an indicator of a nonprofit’s reach. Please help us spread the word about our work.

Donate frequent flyer miles.Aeroplan, Air Canada‘s frequent flyer program, is matching all donations of Aeroplan miles 1:1, up to 500,000 miles, this week. Your donated miles help in many ways. The flights get our team to the field, bring top scientists and aspiring young biologists to join us, let us bring our skills to other countries to help build capacity in lower-income countries, and ultimately, to take the information to the meetings where important conservation decisions are made. Aeroplan even offsets the carbon footprint for every flight we redeem through this special program.

Thank you so much for your help. We are starting to see some real-world conservation successes emerging from our work on ocean noise and marine mammal bycatch in fisheries. Thank you for allowing us to do that work.

Today, 22 April 2017, marks the 48th time that people around the world celebrate Earth Day. Since 1970, the effects of climate change have become undeniable, but the environmental news is not all bad. The voices of 1970s environmental grassroots movement were heard, and that public pressure led the USA to pass some of the most powerful legislation anywhere to protect endangered species and their habitat. Given our focus, it’s not surprising that we see the Marine Mammal Protection Act as one of the best examples of grassroots movements leading to real-world conservation gains. Over the last few decades, consumer demand has shifted fisheries practices to the extent that “dolphin-safe tuna” is now the industry standard in North America and Europe. Similar efforts drove the Save the Whales movement, which led to a moratorium on commercial whaling in 1986. We’re not naive, but we are inspired by #OceanOptimism.

After every public lecture we give, people ask how they can help.

People often share feelings of hopelessness and powerlessness in the face of global losses of biodiversity and wilderness. The paradox is that collectively, we hold the power to influence policy, and with every purchase we make, we have the power to influence markets and industrial practices. We cast a vote every time we buy – or choose not to buy – a product. And we are struck by the energy in today’s March For Science events around the world. The people have spoken, and they want policy to be based on reliable evidence. Our tagline, Science for the Sea, tells you that we share that view.

Here are some examples of the power of consumer choice that have inspired us lately. This is not an exhaustive list, and it draws heavily from personal experience. When have you “voted” or made a sustainable choice with your dollar? We’d love to hear from you in the comments.

Don’t buy what you don’t need. Our friends at Patagonia blew us away in 2011 with their New York Times ad asking people not to buy their products. Prevention is far better than a cure.

Reuse and upcycle. Last year, Patagonia donated their entire Black Friday sales to environmental programs like ours. Reusing or repurposing products is far more resource-efficient than recycling.

Buy locally. As Rose George wrote in her gorgeous book, 90% of all the goods we purchase were shipped overseas. Support local businesses and reduce your environmental footprint. Our friend, Alexandria Rossoff, has run a thriving jewelry business in Seattle for 38 years that seamlessly integrates sustainability by reusing estate jewelry and catering to a local market. As she launches an online business model to spend more of her time on her conservation mission, we were touched that Alexandria has decided to donate a portion of her last month’s in-store sales to our nonprofit. Thank you!
